Quantum Cryptography

This programme is rather similar to that of Quantum Computers.
Owing to the enormous amount of information which a
noiseless quantum-mechanical system can store, certain
tasks may be carried out, using such systems, at
fantastically high speeds. For example the product
of two enormous prime numbers may be factorized in
milliseconds, whereas the same task would take weeks
on the most powerful CRAY computer. (Give a Web page.)

The programme is doomed to fail for roughly
the same reason as Quantum Computers.
Noiseless QM systems are a myth because the zeropoint
noise is present even at zero degrees Kelvin. Many
banks and military organizations have been
persuaded to fund research in this area. It will
be interesting to see their reactions when they
discover how some scientists have duped them --
and themselves at the same time!
